Ellipta is a respiratory device that is a successor of the Diskus. A major difference between the devices is that Ellipta, especially the 2-strip type, includes a pair of blisters rather than a single blister as contained in Diskus. This study aimed to compare the particle-release properties and mechanical features of both devices. ⋯ The Ellipta required lower inspiratory flow than Diskus, which arises from a higher distribution to blister flow. Ellipta may be preferable to Diskus for patients with impaired pulmonary function.

Observational Study
Oxygen Desaturation and Persistence of Symptoms during Activities of Daily Living in Patients following Hospital Discharge for COVID-19.
COVID-19 can cause respiratory and multisystemic impairments, which lead to impaired activities of daily living (ADL). Telemonitoring after discharge from the hospital may help identify the persistence of such limitations during ADLs simulations. The aim of this study was to compare SpO2 , fatigue, and dyspnea through telemonitoring during a battery of 4 ADLs in patients following hospital discharge for COVID-19. ⋯ SpO2 was similar among the ADLs but walking triggered desaturation in a larger number of subjects. The subjects presented with mild-to-intense fatigue and dyspnea during ADLs 30 d after discharge after hospitalization for COVID-19 regardless of desaturation status, which demonstrated that the persistence of symptoms is independent of hypoxemia during exercise.

Pediatric extubation failure is associated with morbidity and mortality. The most common cause is upper-airway obstruction. Subglottic edema is common, but upper-airway obstruction can occur from the oral cavity to the trachea. Dichotomous categorization of extubation failure as airway versus non-airway may help identify risk factors as well as strategies that translate to lower extubation failure rates. ⋯ Airway extubation failure prevalence was 1.5 times higher than non-airway failure. Potential risk factors for airway failure were identified. These findings are hypothesis generating for future study focused on key evidence gaps and pragmatic bedside application.
